Let’s start here: I don’t care one bit about the hairline of LeBron James.

But for whatever reason, it has been a hotly-debated topic among fans for several seasons.

There have been dissections of the sizes and angles of the headbands that James has worn over the years, and side-by-side photo comparisons made (like the one below from Sporting News) to try to prove that work has been done.

Barber Nick Castemanos has grown tired of getting asked over and over again about the hairline of his most famous client, LeBron James.

“There is no dye. No additives. No preservatives,” Castemanos told Yahoo Sports in a phone interview Thursday. “Everyone thinks he’s dying his hair using [temporary hair colorings] Bigen or Black Ice. It’s all his hair. They still don’t believe me. I get Bigen comments all the time.

“I’ve become numb to it. It used to bother me. It’s not easy to hear that.”

Bigen is the stuff that, when used in excess, can make you look ridiculous — just ask Carlos Boozer about that. But evidently, when used properly, it could be responsible for fixing a hairline’s problems.

In a layman’s hands, Bigen is nothing more than semipermanent hair dye. But in the hands of a master barber, Bigen becomes a fountain of inky youth applied in such a way that a razor-sharp hairline can be shaped and manipulated, or tufts of hair sprouted on the face look like a full mass of beard. Hairlines are sculpted tightly back into their starting blocks; beards become so sharply angled that pro skiers would be wary of those slopes.

It appears as though something has happened to make LeBron’s hairline snap back into shape. If it was a transplant procedure of some kind, then technically, the hair we’re now seeing on his head would indeed be “all his.”

As I mentioned at the top, I couldn’t care less about this. But for those who continue to be obsessed, you can check out the photo below and decide for yourself.

Game 4 of the NBA Finals was the 50th officiated by longtime referee Joey Crawford, and while he managed to stay out of the spotlight for the most part, he did have one memorable exchange.

Crawford was caught telling either Cavaliers big man Timofey Mozgov or Warriors defensive ace Draymond Green to “do me a favor and shut up,” and while this may not seem to be the most professional way of communicating, keep in mind that officials are often berated by players and coaches throughout the game, and are subjected to hearing far worse.

Make sure to check out Warriors’ assistant coach Alvin Gentry taking all of this in on the sidelines; his reaction, a combination of shock and amusement, is priceless.

J.R. Smith has been a key contributor for the Cavaliers for the bulk of the season.

But he’s been dismal in a reserve role during the NBA Finals, at the time his team needs him the most.

LeBron James has been desperate to find help on the offensive end of the floor in this series, but only Matthew Dellavedova (at least before Game 4) had provided it on anything resembling a consistent basis. Cleveland needs Smith to do much better than the 29.7 percent he’s shooting in the Finals, but to this point he’s been unable to find his way.

Smith owned up to his poor play postgame, with a colorful, honest description of how things have been going.

Q: You aren’t shooting the way you want to throughout The Finals. How can you change that?

Smith: Stop thinking so much and just go out there and play. Be more than just a shooter, go out there and defend, rebound and create plays for everyone else. …

Q: How would you assess your own game right now?

Smith: Horses—.

Smith’s father believes his son will break out of his slump soon, and do so in thrilling fashion.

“I think he jumped into the cameraman,” Bogut said when asked to give his perspective on the play. “Yeah, I think he came down and took two steps and then fell into the cameraman. I definitely, definitely didn’t hit him that hard.”

When the reporter replied by saying, “That’s how you saw it?” Bogut said, “No, that’s how it was. If you look at the replay, you can see the two steps being taken and then him falling into the camera. That’s what we saw on the replay, and that’s what my teammates saw.”

James could have tried to exaggerate the contact in order to convince the officials that a flagrant foul should be called. But it seemed as though James was simply off balance when he landed, and stumbled a few steps to fall in the least dangerous way possible.

Bogut, who played less than three minutes after Steve Kerr took him out of the starting lineup in favor of Andre Iguodala, obviously sees things differently.
